Method for forming game content group, computer-readable, non-transitory medium, and computer

1. A method for forming a game content group performed by a mobile computing device, the game content group formed by a plurality of game contents to be used in a game, the method comprising:

storing a first state of the game content group in a storage module;

changing the game content group to a second state according to detection of an operation performed by a user in the game;

sensing a shake of the mobile computing device, by a shake sensor;

detecting a shake of the mobile computing device based on information output from the shake sensor, by a shake detector; and

restoring the game content group to the first state when the shake detector detects the shake of the mobile computing device.

2. The method of forming a game content group according to claim 1 , wherein

an initial state of the game content group is stored as the first state in the storage module, and

the game content group is restored to the initial state, when detecting a shake for a predetermined number of times or more in a predetermined time period.

3. The method of forming a game content group according to claim 1 , wherein

an immediately previous state of the game content group is stored as the first state in the storage module, and

the game content group is restored to the immediately previous state, when detecting a shake for once in a predetermined time period.

4. The method of forming a game content group according to claim 3 , wherein, when the game content group is changed, the state of the game content group after the change is stored in the storage module.

5. The method of forming a game content group according to claim 1 , wherein

the operation module is a touch screen, and

when two game contents among the game contents constituting the game content group are tapped on the operation module, the positions of the two tapped game contents are switched.

6. The method of forming a game content group according to claim 1 , wherein

the operation module is a touch screen, and

when one game content among the game contents constituting the game content group is slid, on the operation module, to a position of a different one of the game contents constituting the game content group, a position of the one game content and the position of the different one of the game contents are switched.

7. A computer-readable, non-transitory medium storing a computer program, wherein the computer program causes a computer which includes an operation module, and which forms a game content group formed by a plurality of game contents to be used in a game, to execute a process, the process comprising:

storing a first state of the game content group in a storage module;

changing the game content group to a second state according to detection of an operation performed by a user in the game;

sensing a shake of the mobile computing device, by a shake sensor;

detecting a shake of the mobile computing device based on information output from the shake sensor, and

restoring the game content group to the first state when detecting the shake of the mobile computing device.

8. A computer for forming a game content group formed by a plurality of game contents to be used in a game, comprising:

an operation module;

a storage module for storing a first state of the game content group;

a game-content-group changing module for changing the game content group to a second state according to detection of an operation by a user in the game via the operation module;

a shake sensor for sensing a shake of the mobile computing device;

a shake detection module for detecting a shake of the mobile computing device based on information output from the shake sensor; and

a game-content-group restoring module for restoring the game content group to the first state when the shake detection module detects the shake of the mobile computing device.
